Yes, surely you can, and another solution (way better) is to ignore them altogether, and enjoy your 'already perfect' game. I've been in this forum for a while, and I know loot-related thread just by looking at the title, I sure you can too.
Sarcasm aside, I think that regarding the update feedback, all opinions are equally valuable, either for/against or indifference. You can explain your reasons however you want, but in the macro prospective, they all boil down to those 3 categories. Most of the time, people just create an account, and say "loot sucks" then leave. I don't think that those posts are completely useless, they do hold some values. Those posts are part of the casual (which is the majority of the population), who're dedicated enough to go into the forum, create an account and report their current experience. Now if nothing had changed for the worse, no one would have done it. Now when SC actually show a sign that they're listening to the feedback, that's where the more constructive feedback coming in. We need to gain attention first, then explain them later.
SC has created a thread for all the complains to go to, but it is no way a "discussing" thread (at least not in a sense of interactive discussion where SC shows a sign that they actually listen to people problems). It's only natural for those people to feel that they're ignore; thus, creating a new thread will gain them more attention. SC probably won't care either way, but this is a method that people use to emphasize the problem. I understand that mentality. They're trying, that's all, no harm done to any of you.
P/s: I know that loot complaining has always been there in the forum, but this is the biggest one yet (since the infamous inactive base search code event).
